• Proposing a multi-channel medium access control (MAC) protocol forhybrid VLC/Wifi networks
– The proposed MAC protocol is based on an integration of two standards, IEEE802.15.7 VLC and IEEE 802.11 Wifi CSMA/CA(s)
– Newly add on top of current MAC protocols a sub-layer that runs dynamicchannel selection by taking intelligent control decisions, regarding channelaware and traffic aware.
– System performance metrics are analytically studied based on a combinationof queuing and Markov chain theories

• Studying an application of quantum key distribution (QKD) for indoorvisible light communication (VLC) networks
– Designing and analyzing the security performance of the QKD protocol based on sub-carrier intensity modulation (SIM) over indoor VLC systems taking into account theeffects of VLC channel and other physical layer impairments
– Deriving the mathematical expressions for quantum bit-error rate (QBER) and secret-key rate. Based on the mathematical expressions, various systems’ metrics, includingthe modulation depth and the dual-threshold scale coefficient, can be determined soas to QBER and secret-key rate meet the design criteria
